Your semisubmersible drilling unit is moving onto a location in shallow water with a very hard bottom. What is the most effective means of maintaining your position at this location during severe weather?

Correct Answer: Option C — Piggyback all anchors and pretension to above the expected tensions

Piggybacking anchors (tandem anchoring) doubles holding capacity, while pre-tensioning above expected weather loads ensures the system is fully bedded and proof-loaded, crucial for maintaining position on hard bottoms in severe shallow-water environments.
